Bulletproof Intermittent Fasting: Lose Fat, Build Muscle, Stay Focused & Feel Great

Bulletproof Intermittent Fasting: Lose Fat, Build Muscle, Stay Focused & Feel Great

If you want to lose fat and improve your health as fast as possible, without feeling mentally slow, it’s hard to beat Bulletproof Intermittent Fasting. Here’s an overview of the protocol, which I lay out in more detail in my new NYT bestseller The Bulletproof Diet. Plain intermittent fasting has become popular in biohacker circles because it shows tremendous promise for fat loss, preventing cancer, building muscle, and increasing resilience. The most popular site that covers plain intermittent fasting is Leangains.com. It’s totally worth a visit. The basic idea behind plain intermittent fasting is to eat all of your daily food in a shortened period (8 hours in the case of Lean Gains) and fast the rest of the time. For reasons we will get into below, this tells your body to simultaneously build muscle and burn fat. It really works. The problem is not everyone does well with fasting. If you’re a busy entrepreneur or even a student who needs to be in a high performance state all day, dealing with hunger can be a distraction. It’s much worse for those with an impaired metabolism (i.e. the people who need to lose weight). If you have more than 30 pounds of extra fat or if you’re facing diabetes, it can be hard to skip meals and still get things done. As explained in The Bulletproof Diet book, Bulletproof Intermittent Fasting is an easy biohack that changes that and makes it possible to lose fat and build muscle faster than plain intermittent fasting… without feeling hungry or tired. Introducing Bulletproof Intermittent Fasting Bulletproof Fasting is the same as intermittent fasting, except you consume a cup of Bulletproof Coffee in the morning. The healthy fats from grass-fed butter and Brain Octane Oil give you a stable current of energy that sustains you thro Continue reading >>

Ketogenic Dieting And Intermittent Fasting – It Really Works!

Ketogenic Dieting And Intermittent Fasting – It Really Works!

I’ve been combining ketogenic dieting and intermittent fasting for quite some time now. Two weeks ago a colleague of mine, who is trying to lose weight herself, put me up to a challenge. Starting on Friday the 15th of January, we both had until Friday the 19th of February to lose as much weight as possible and whoever has lost the most by then wins $50. The rules are: Weight loss must be safe, ie. healthy eating, low calories and moderate exercise. No going days on end without food and trying to exercise for hours every day. If neither of us lose at least 5kg by the end date, neither of us win. Important afternote: I ended the challenge losing a whopping 7.2kg (15.8 lb) of FAT (a total loss of over 10kg when counting the initial 3kg of water weight lost before starting the competition). I did this entirely through ketosis fasting. Read on if you want to lose weight as fast and easily as I did! My Secret Weapon As I have a trip to Japan coming up shortly after the end date and had wanted to lose a lot of weight before then anyway (I gained 5kg in 3 weeks last time I was in Japan!), I accepted the challenge. We’re now 2 weeks and 1 day into the challenge and I’d like to share my results, as well as some weight loss tips I’ve learnt in these short 2 weeks. Ketogenic Dieting and Intermittent Fasting really works! Of all the people in the world, it was my gastro-enterologist who introduced me to “the 5-2 diet“. For those who don’t know what the 5-2 diet is, it’s basically a form of intermittent fasting where you eat normally for 5 days, and eat 1/4 of your usual target daily energy expenditure on 2 days. Using the TDEE calculator I just linked, I found that for weight maintenance (neither losing nor gaining weight) I would need to consume (note: consume. Not Continue reading >>

Autophagy: The Real Way To Cleanse Your Body

Autophagy: The Real Way To Cleanse Your Body

For the last time, forget juice cleanses and detox diets. They’re fluffy nonsense words. While there’s probably nothing wrong with drinking your weight in liquid kale, it won’t flush out toxins any faster than if you were eating, you know, actual food. The good news: There's a little-known way your body does cleanse itself, and it’s a process that you can control. All you need to do is practice a little self-cannibalism. What? Yes, you can actually train your body to eat itself—and believe it or not, you want it to. It's a natural process called autophagy (literally “self-eating”), and it’s the body’s system of cleaning house: Your cells create membranes that hunt out scraps of dead, diseased, or worn-out cells; gobble them up; strip ’em for parts; and use the resulting molecules for energy or to make new cell parts. “Think of it as our body’s innate recycling program,” says Colin Champ, M.D., a board-certified radiation oncologist, assistant professor at the University of Pittsburgh Medical Center, and author of Misguided Medicine. “Autophagy makes us more efficient machines to get rid of faulty parts, stop cancerous growths, and stop metabolic dysfunction like obesity and diabetes.” There’s also evidence that the process plays a hand in controlling inflammation and immunity. When scientists engineer rats that are incapable of autophagy, they’re fatter, sleepier, and have higher cholesterol and impaired brains. To sum it up, autophagy is key to slowing the aging process. And you can learn how to do it better. 3 Ways to Self-Destruct "So how do I eat myself?” is a question you probably haven’t asked before, but we’re about to tell you. First of all, autophagy is a response to stress, so you’re actually going to want to put your Continue reading >>

The 7-10 Day Water Fast

The 7-10 Day Water Fast

After you feel comfortable with the three-day water fast and your body can make the switch to ketosis without much fuss (more info here), then it’s time to consider the 7-10 day water fast. For it’s only after you begin drawing solely on the energy of fat cells that the process of detoxification can kick into a higher gear (more info here). This means that the three-day fast simply isn’t enough to confront any deeper issues you want to heal. If you’ve found it difficult to get through your first few three-day water fasts, it’s only understandable that the thought of a 7-10 day fast seems even more daunting. For this reason, I offer private online consultation as a fasting guide (click here). Despite any doubts and fears emotionally, physically 7-10 day fasts tend to go more smoothly than you might first expect (so long as you’re healthy and don’t have any serious issues with detox). This is because your body does the hardest work in the first three days while it establishes ketosis – during which your fuel tanks are also running on empty. From the third day on, ketosis continues to become increasingly efficient, and so you’ll feel lighter and fuller with energy, like a well oiled machine. Increasingly, the fast feels like a celebration of freedom from the daily need to eat food. This freedom, as well as a lighter body and clearer consciousness, can feel so good that many people actually experience a sense of reluctance in returning to food at the end of the fast. There really is a beautiful purity about just being, without the needs and addictions of food distracting you, weighing you down. As your healing metabolism finishes establishing itself by the end of the third day, the digestive system also finishes shutting down its normal function. As a resu Continue reading >>

Peak Fasting — How Long Should You Intermittently Fast?

Peak Fasting — How Long Should You Intermittently Fast?

Intermittent fasting helps reset your body to burn fat for fuel, and helps optimize insulin sensitivity and mitochondrial health and energy production Intermittent fasting involves cutting calories in whole or in part, either a couple of days a week, every other day, or even daily. It’s one of the most effective interventions for normalizing your weight Fasting has a number of health benefits, including improved cardiovascular health, reduced cancer risk, gene repair, increased longevity, and dementia prevention By Dr. Mercola Do you struggle with excess weight? Are you showing signs of insulin and leptin resistance? Is your fasting blood sugar above 100? If you answer yes to one or more of these questions, you may want to reconsider not only what you eat but when you eat as well. One lifestyle factor that appears to be driving not only obesity but also many chronic disease processes is the fact that we eat too frequently. Research reveals that a vast majority of Americans eat all day long.1 Most also consume a majority of their daily calories late in the evening, and this type of eating pattern is a recipe for weight gain and metabolic dysfunction. The reason so many struggle with their weight (aside from eating processed foods that have been grossly altered from their natural state) is because they rarely, if ever, skip a meal. As a result, their bodies have adapted to burning sugar as its primary fuel, which down-regulates enzymes that utilize and burn stored fat. In addition, our ancestors didn't have access to food 24/7, and biologically your body simply isn't designed to run optimally when continuously fed. Biological Repair and Rejuvenation Occurs During Fasting Research has confirmed that many biological repair and rejuvenation processes take place when there' Continue reading >>

Water Fasting Ketosis Is Where The Fat Burn Heaven Begins

Water Fasting Ketosis Is Where The Fat Burn Heaven Begins

In this guide, you will learn everything you need to know about water fasting ketosis. I'll explain how water fasting can help you reach your absolute highest possible fat burn rates, which is easily the single biggest benefit of ketosis. You'll also see the science on how long it actually takes before you can enter ketosis during a water fast. You'll also learn about one of the most dangerous problems of water fasting ketosis. I'll also tell you why it is a very good idea to avoid one of the most common mistakes people make once they already reach ketosis during a water fast. Now that you know what you're getting yourself into, here's a quick overview of everything that's covered in this guide: The single biggest benefit of water fasting ketosis Simply put, ketosis is a state where you get to enjoy your absolutely highest possible fat burn rates. If you're on your regular diet, your body can draw energy from a couple of different sources (so not just from your body fat reserves). Those other, non-fat energy sources are the main reason why your fat burn rates stay on the low end, even if you start eating less food. But during a water fast, because you're eating no food at all, those other energy sources in your body will be completely wiped out after a while. Once that happens, your body will enter full ketosis, and in that state of full ketosis, your body will have no choice but to rely almost exclusively on your body fat reserves. With no other energy sources available, ketosis will trigger some pretty amazing fat burn rates in your body. Water fasting is one of the fastest ways to reach that state of super high fat burn. And a lot of people do a water fast just for this reason. There's only one problem with reaching ketosis through water fasting. PRO TIP: A different Continue reading >>

How To Get Into Ketosis In Less Than 3 Days

How To Get Into Ketosis In Less Than 3 Days

Do you need to get into ketosis super fast? Don't think you can handle the deprivation and hunger of a water fast? The good news is that you don't have to. You can rev up your metabolism, escape hunger, and be on your way to fat burning in one or two days! All it takes is a ketogenic diet that is lower in carbs than standard keto. This will cut your cravings to the bone and switch you from a glucose burning metabolism to burning fat faster than anything else! Ketogenic diets work by reducing basal insulin levels, lowering blood triglycerides, and setting up conditions that will move you into the state of nutritional ketosis. Getting into ketosis is important because when the body produces ketones, your hunger level goes down, your energy goes up, and you experience a state of well-being. All of these benefits will make it easier for you to stick to your low-carb diet plan. On a typical keto diet, it takes 3 to 5 days to enter into the state of ketosis. But how quickly you do that depends on how many carbohydrates you were eating per day before you started restricting them. In addition, if you're looking for the urine testing strips to change colors right now, that only occurs once ketosis is well under way. Most low-carb diets start you off at 20 to 30 net carbs. Atkins 20 and the Reddit version of Keto begin at 20 net carbs, and the Protein Power Lifeplan begins at 30. These amounts are low enough to get the job done within a few days. If you're coming from a carb-heavy diet, it might take a little longer to switch metabolic pathways than if you're merely switching from a low-calorie plan to Atkins, Keto, or LCHF. However, there is a much quicker method that you can use right now instead of these standard Keto diets. The quick-start method I'm going to share with you i Continue reading >>

7 Tips To Get Into Ketosis

7 Tips To Get Into Ketosis

Ketosis is a normal metabolic process that provides several health benefits. During ketosis, your body converts fat into compounds known as ketones and begins using them as its main source of energy. Studies have found that diets that promote ketosis are highly beneficial for weight loss, due in part to their appetite-suppressing effects (1, 2). Emerging research suggests that ketosis may also be helpful for type 2 diabetes and neurological disorders, among other conditions (3, 4). That being said, achieving a state of ketosis can take some work and planning. It's not just as simple as cutting carbs. Here are 7 effective tips to get into ketosis. Eating a very low-carb diet is by far the most important factor in achieving ketosis. Normally, your cells use glucose, or sugar, as their main source of fuel. However, most of your cells can also use other fuel sources. This includes fatty acids, as well as ketones, which are also known as ketone bodies. Your body stores glucose in your liver and muscles in the form of glycogen. When carb intake is very low, glycogen stores are reduced and levels of the hormone insulin decline. This allows fatty acids to be released from fat stores in your body. Your liver converts some of these fatty acids into the ketone bodies acetone, acetoacetate and beta-hydroxybutyrate. These ketones can be used as fuel by portions of the brain (5, 6). The level of carb restriction needed to induce ketosis is somewhat individualized. Some people need to limit net carbs (total carbs minus fiber) to 20 grams per day, while others can achieve ketosis while eating twice this amount or more. For this reason, the Atkins diet specifies that carbs be restricted to 20 or fewer grams per day for two weeks to guarantee that ketosis is achieved. After this point, s Continue reading >>

Extended Fasting?

Extended Fasting?

What does an extended water only fast (5-10 days) do to the body? A five-day fast and ten-day fast are very different because ketosis increases steeply during that time. In this answer I'll describe a fast of seven to ten days because of the possibility that it may kill cancer cells. Thomas Seyfried, a scientist who does a lot of research in this area, thinks we need to fast at least seven days to make this happen. Therefore, a five day fast may not be worth the trouble. Seyfried recommends from seven to ten days. It should be said that no matter how long you plan to fast, you should forget your plan and stop immediately if your body shows signs of distress. We can look at ketone levels to understand the difference between fasts of different lengths. Longer fasts produce higher ketone levels, as shown in the following graph: As you can see from the graph, the area under the curve is much greater during the second five days than the first five days. You can also see that ketosis doesn't max out until day 30. It takes a long time for the body to get fully into ketosis. Your experience during the first few days of a fast will vary depending on whether you are already ketoadapted. If not, you will feel crummy. You will crave carbs. As the days go on, your brain will become more ketoadapated and your cravings for carbs and your overall hunger will diminish. On long fasts, people aren't hungry. However they think about food all the time -- it's very strange! On my 30-day fast I used to read cooking websites for hours every day, yet I felt no desire to walk to the refrigerator and eat anything. Other people report the same thing. During a ten-day fast, blood ketone levels rise to about 6 mmol/L which is higher than levels attained on the kinds of diets described as ketogenic o Continue reading >>

No action or inaction should be taken based solely on the contents of this information; instead, readers should consult appropriate health professionals on any matter relating to their health and well-being. On the whole, Paleo is fasting-positive. Intermittent fasting is a powerful tool for improving health, jump-starting weight loss, or beating cravings, and there’s plenty of medical literature to back up its usefulness. But what about longer fasts (more than a day or two)? If intermittent fasting is good, will a longer fast be even better? Long-term fasting can take several different forms. The most extreme is a “dry fast,” consuming nothing at all (food or water). This is definitely not advisable, as it’s very dangerous to go for more than a day or so without drinking. Water fasting means drinking only water, but consuming no calories during the fast. Another technique is juice fasting, or consuming only fruit and vegetable juices. Some people also fast on broth, or extremely low-calorie protein mixes. Juice fasting and bone broth fasting aren’t truly fasts, since they do involve some intake of calories and nutrients. And protein fasts can be downright dangerous, since humans just weren’t built to live on protein with no accompanying fat. This article focuses on water fasting: the benefits, the drawbacks, and precautions to take if you do decide to start a longer fast.

5 Simple Steps To Get Into Ketosis

5 Simple Steps To Get Into Ketosis

I think almost everyone agrees with me when I say that the ketogenic diet is probably one of the most complex and difficult eating plans out there. Even when you’re not on a diet or trying to lose weight you still have to bring a lot of attention to detail. Getting into ketosis isn’t as important as we would think, but there are still 5 simple steps we can make to get into a ketotic state. What Needs to Happen The conditions of nutritional ketosis are: Low blood sugar levels (about <85 mg/dl) Low insulin And because of that there are going to be: Higher glucagon, which is released by the liver, in response to low insulin, to increase the amount of fatty acids in the blood stream. High serum blood ketone levels, with the optimal zone being in between 0.5 and 3.0 mMols. Here are the 5 simple steps to get into ketosis. Step #1 Do a 24-Hour Fast Ketosis is the by-product of a prolonged period of fasting. After your liver glycogen stores have been depleted already after an overnight fast, the liver then begins to create more ketone bodies. After 2-3 days of fasting, you’ll be definitely in ketosis. Your brain will adapt to using ketone bodies and gets about 75% of its energy from fat. Overall, the body’s glucose demands and protein catabolism get reduced to a bare minimum. However, to get into ketosis we don’t necessarily have to abstain from eating that long. We’re already in mild ketosis in the morning and doing a 24-hour fast will increase our ketogenic pathways by a significant amount. Step #2 Start Eating Low Carb Ketogenic Meals Once you finish your 24-hours, you can start eating keto foods. Make your first meal something extremely ketogenic, meaning: Ultra-low carbs – cruciferous vegetables, like spinach, kale, broccoli, cauliflower, cabbage, chard. Your Continue reading >>

Tim Ferriss – 3 Day Fast Protocol Details – Get Into Ketosis Quicker And Easier

Tim Ferriss – 3 Day Fast Protocol Details – Get Into Ketosis Quicker And Easier

In Tim Ferriss’ new book Tools of Titans he puts forward a method to optimize the process of fasting. In his typical 80/20 style, he aims to get the most benefits, in the least amount of time. His recommended fast is conducted in a 3 day period, spanning Thursday evening to Sunday evening. 3-Day Fast Overview Stop eating Thursday night Friday morning go for a long walk to accelerate your transition into ketosis Friday and Saturday stay fasted, and consume moderate amounts of exogenous ketones and MCT oil (as needed), to give you a boost while you’re keto adapting. Sunday evening you break the fast. Here’s the process in more detail if you don’t have Tools of Titans to hand: Thursday Evening Eat a low carbohydrate dinner around 6pm. Make that the last meal of the day. Go to bed as normal. Friday Morning Drink some caffeine if needed, then get out the door and walk within 30 minutes of waking. Bring at least 1 litre of water, with some added salt (to prevent headaches/cramping), and sip as you walk. Walk for 3-4 hours(!). Filling up/buying more water as needed. Arrange phone calls for this time, to make the time productive. The idea behind the walk is that you use up your glycogen stores, forcing your body to move quicker into deep ketosis. The quicker you get into ketosis, the less time you spend feeling sub-optimal, and the less potential muscle wastage. Friday Day (post walk) Consume exogenous ketones or MCT oil 2-3 times throughout the day, where necessary. Tim primarily uses KetoCaNa & KetoForce as exogenous ketone sources. Both these products contain 11.7g of Beta-hydroxybuterate per serving, and each contain 16 servings. The key difference is that KetoForce is an unflavoured (alkaline) liquid. And KetoCaNa is an orange flavoured powder you can mix into wate Continue reading >>

The Easiest Way To Get Into Ketosis

The Easiest Way To Get Into Ketosis

For some people, Keto can be something mystical and always out of their reach. Indeed, it’s difficult to establish a state of nutritional ketosis, but everyone can do it by using the easiest way to get into ketosis. Getting into ketosis requires these conditions to be met. Liver glycogen stores (100-150 grams of glucose) have been depleted and the liver starts converting fatty acids into ketone bodies. This takes approximately 16 hours or so. The concentration of serum blood ketone levels is above 0.5 mMols, optimally not higher than 3.0 mMols. Blood sugar and circulating insulin have dropped significantly, while not causing a hypoglycemic response. You can accomplish it with two things: Fast for an extended period of time Restrict your carbohydrate intake to close to zero for a few weeks Both of them are almost identical – fasting induces ketosis, and the ketogenic diet mimics the physiology of fasting to a great degree. There’s not much difference between fasting ketosis and nutritional ketosis. The only distinction is what physiological state your body is in, but they still have a few unique traits. Fasting Ketosis – You haven’t consumed any calories for 24+ hours and thus experience higher levels of blood ketones. In addition, you’ve elevated the metabolic pathway called ‘autophagy’ that causes cellular repair and maintenance. Nutritional Ketosis – You’ve established ketosis by restricting carbohydrates to almost zero and have depleted liver glycogen that way. Ketone bodies get created but you’re still in a fed state, thus suppressing autophagy. While getting into fasting ketosis takes about 1-3 days, nutritional ketosis requires 2-3 weeks of keto-adaptation, during which you need to stay close attention to how many carbs and protein you eat, a Continue reading >>

Blog #7: Water Fasting And Keto

Blog #7: Water Fasting And Keto

Blog #7 Fasting and Keto This is a personal anecdotal commentary on Fasting and the Ketogenic diet. I am not a doctor, so the below is my understanding of fasting and its effects on your body. In the early '80's I read a small book on the benefits of fasting. Fasting is the fastest way to get your body into the state of Ketosis. Ketosis is when your body has switched "fuels" that give you energy. After you eat a meal, your body will primarily convert the carbs first. It converts the carbs to sugars and dumps them into the blood. Why the carbs first? I don't know. My guess would be that they are easier to convert. After your carbs get converted/used up, the body switches over to Fats. It converts the fat in your food to fatty acids called Ketones. Unless you eat a heavy meal laden with starchy carbs at midnight, you will switch over to ketosis before you wake up. Then you will eat a meal that breaks your fast. Since fasting deprives your body of all food, your body will go into ketosis rather quickly. If you continue fasting, you will not die for a long time, even if you're a skinny person. You will have to drink water though. You can only last a week or so without water. I have added days of fasting to my road to weight loss. I have many reasons for doing this: Yes, I know fasting is like a starvation diet to the max. Weight loss is very fast. And I am in a hurry to lose a lot of weight. I want to start building my home next spring/summer of 2015. Although the normal Keto diet will allow me to lose weight, its just too slow. I have the "sword of Damocles" hovering over my head, that is, if I don't lose my weight, I will get bariatric surgery and half my stomach will be pared off. I figure that if I did opt to get bariatric surgery, there would at least a week of fasting Continue reading >>
